SCRAPER FOR DISK HARROWS- Specification of Letters Patent.

Patentedfiuly 31,1906.

Application filed October 8, 1904. Serial No. 227,698

To wZZ whom it may concern:

Be it known that we, SAMUEL V. KE NEDY and CHARLEs S. SHARP, citizens ofthe United States, residing at Auburn, in the county of Cayuga and Stateof New York, have invented a certain new and useful Improvement inScrapers for Disk Harrows, of which the following is a specification.

Our invention relates to that class of scrapers for disk harrows inwhich the scrapers are movable toward or from the disks and the objectof our invention is to simplify and perfect the construction of suchscrapers and to lessen the cost of their manufacture.

Referring to the drawings forming part of this specification, Figure 1is a rear view of a gang of disks, showing our improved scrapersattached. Fig. 2 is an end elevation of the same, omitting the lever;and Fig. 3 is an enlarged detail view inpart section.

The disks A are journaled upon anaxle B and s aced by spools C in theusual manner. Stan ards D connect the disk gang with the gang-beam E,which has secured to it supports F F, slotted at their outer ends tocarry the scraper-bar G, the slots being sufficiently large to permit alongitudinal movement of the scraper-bar.

Brackets H are pivotally mounted upon the scraper-bar G and havedownwardly-projecting arms I, to which the scraper-blades A are rigidlysecured in any suitable manner. Sockets J areformed in the brackets Hand are slotted at the top to admit the lower edge of the scraper-barGr. Coiled springs g are within the sockets J and contact with thebottoms thereof and with the scraper-bar Gr, beirg retained in thesockets by the scraperbar,'so that while there is a certain. amount ofresil ency in the scraper-blades A, a more perfect and yielding contactwith the disks is insured. Lips or projections c are formed upon thebrackets H and by contact with the scraper-bar G limit the movement ofthe brackets and scrapers toward the disks.

Pivoted upon the scraper-bar at a is a crank-arm (1,, having a lever bbolted to it,

' and a link I), hooked in an eye a and adjustably connected to thesupport F, so that it is apparent that when the lever b andconnectposition against the dis s and are so held by reason of the factthat the link I) is thrown below the centerof-the pivotal point ofthecrank-arm a. Thescrapers are moved out of engagement with the disksby a reverse movement of the lever, lines, Fig. 1.

Having thus described our lnvention, what We claim, and desire to secureby Letters Patent is 1 The combination With the disks, of a scraper-bar,scraper-carrying brackets p voted thereon, sockets in the bracketscontaining springs in contact with the scraper-bar, and slots in saidbrackets with which the scraper-bar engages. I

2. In a scraper for disk harrows, the com bination of a scraper-bar, apivoted bracket thereon carrying a scraper-blade, a socket 1n thebracket, a spring therein in contact with the scraper-bar on one side ofthe brackets pivot, and a lip or projection on the bracket to engagewith the scraper-bar on the other side of the pivot and limit theforward moveas shown in dotted ment of the bracket by the action of thespring, the socket having a slot engaged by the scraper-bar.

3. In a scraper for disk harrows, the combination of a scraper-bar, abracket pivoted thereon and carrying a scraper-blade, a socket in thebracket containing a sprlng, and a slot in the socket with whichthescraper- .bar engages to hold the spring in the socket.

4:. In a scraper for disk harrows, the combination of a scraper-barconsisting'of arelatively thin flat bar set vertically edgewlse, abracket pivoted to one side of the bar and carrying a scraper-blade, asocket in the bracket on one side of its pivot, a spring thereinreacting against the under side of the scraper-bar, a lip or projectionon the bracket on theotherside of its pivot to l1m1t the forwardmovement of the bracket, and a slot in the socket in which thescraper-bar enga es, whereby the bracket is braced and gui e in itsmovements.

In testimony whereof we hereunto set our hands, this 21st day ofSeptember, 1904., in the presence of two attesting witnesses.
